To draw a flow chart, identify the tasks and decisions that you make during a process, and write them down in order. Then, arrange these steps in the flow chart format, using the appropriate symbols. Finally, check and challenge your flow chart to make sure that it accurately represents the process, and that it shows the most efficient way of doing the job.

Flow charts tend to consist of four main symbols, linked with arrows that show the direction of flow:
1. Elongated circles, which signify the start or end of a process.
2. Rectangles, which show instructions or actions.
3. Diamonds, which highlight where you must make a decision.
4. Parallelograms, which show input and output. This can include materials, services or people.
